Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat capacity which we'll refer to as simply "heat capacity", meaning it takes more energy to increase the temperature of water compared to other substances. This is why water is valuable to industries and in your car's radiator as a coolant. The high heat capacity of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans.

This same concept can be expanded to a world-wide scale. The oceans and lakes help regulate the temperature ranges that billions of people experience in their towns and cities. Water surrounding or near cities take longer to heat up and longer to cool down than do land masses, so cities near the oceans will tend to have less change and less extreme temperatures than inland cities. This property of water is one reason why states on the coast and in the center of the United States can differ so much in temperature patterns. A Midwest state, such as Nebraska, will have colder winters and hotter summers than Oregon, which has a higher latitude but has the Pacific Ocean nearby.

If you leave a bucket of water outside in the sun in summer it will certainly get warm, but not hot enough to boil an egg. But, if you walk barefoot on the black asphalt of a street in the southern portion of the United States in August, you'll burn your feet. Dropping an egg on the metal of my car hood on an August day will produce a fried egg. Metals have a much lower specific heat capacity than water. If you've ever held onto a needle and put the other end in a flame you know how fast the needle gets hot, and how fast the heat is moved through the length of the needle to your finger. Not so with water.

Why heat capacity is important

The high heat capacity of water has a great deal to do with regulating extremes in the environment. For instance, the fish in this pond are indeed happy because the heat capacity of the water in the pond means the temperature of the water will stay relatively the same from day to night. They don't have to worry about either turning on the air conditioner or putting on their woolen flipper gloves.

Lucky for me, you, and the fish in the pond to the right, water does indeed have a very high heat capacity. One of water's most significant properties is that it takes a lot of heat to it to make it get hot. Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1°C. For comparison sake, it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.

If you'd like to learn more about heat capacity even at the molecular level, check out this video on the specific heat of water from Khan Academy.

This amazing revision App will test your Physics knowledge in one-minute bursts! The free version includes one topic to get you started, and you can upgrade to full course coverage for just £1.99.

* Hundreds of quick-fire questions - all perfectly matched to the AQA GCSE Physics course
* Snack-sized 60-second tests - it's your brain versus the ticking clock. Good luck!
* Every answer fully explained - so it's simple to check anything you got wrong
* Win sparkly trophies - and post them on social media to impress people on the internet

After all that practice, you'll be at the top of your game when the exams arrive.

Version 1.0.5

Ok, but.....

It's good having the questions there, but why do the tests have to be timed? Having 60 seconds to answer as many questions as possible is a poor way to judge someone's knowledge on a subject. Just have 'x' amount of questions for each test which randomise. I also think it would be much more useful if you could also sign in (if you have an online account), making it possible to look through the material you have purchased. Having it all in one place would be so useful when travelling. The books are great!!

It's fine

It's a good concept, but if the questions weren't timed it would be a lot more helpful.

The god awful update I wish I hadn't of installed...

Beforehand, this app was a virtual book where you could flick to pages in the revision guide and read. (This is handy if you lose or forget your revision guide) Now however, it is a quiz game that you have to pay £1.99 for and it does not contain any pages of the revision guide. Very disappointed...

Ah, you're thinking of the Online Editions of our Revision Guides - these quiz-based GCSE Science Apps are completely separate! If you had a CGP Online Edition on your device, you should still be able to access it via your CGP online account. Drop us an email at customerservices@cgpbooks.co.uk if you're having any problems.
